Green maintainability performance indicators for highly sustainable and maintainable buildings

摘要

The concept of green maintainability provides the building sector with an exciting opportunity to transform itself with highly maintainable and sustainable buildings. It spans throughout the building project delivery process and overarches different building systems. This paper aims to propose a set of critical green maintainability performance indicators for building projects; to minimize the adverse environmental impacts whilst maximizing the functional, safety, energy efficiency and financial performance of the facility. To overcome data deficiency challenges, a qualitative research approach was used in this study; consisting of a systematic literature review and expert interviews. The identified set of green maintainability indicators are validated using a pilot case study of an exemplary building project with highly desirable levels of green maintainability. The identified critical indicators are crucial in the development of a green maintainability assessment system. This study is a significant attempt to promote green maintainability among building professionals to advance the lifecycle sustainability of built environments by seeking to improve facility design processes with capable tools.
